The landlord and tenant signed a rental agreement in June 25, 2013. Tenant moved in on July 1, 2013. In May 2014 the landlord is thinking of not extending the tenants lease but when he checked the lease it has no expiration date. All the while the landlord assumes that the lease will end on June 30, 2014 but apparently the lease is silent on it. Should the landlord notify the tenant that her lease will expire on June 30, 2014 or he needs to issue a 30-day notice to vacate to the tenant? And when?
